Letters Patent No. 93,301, dated August 3, 1869.

IMPROVED SLATE AND METAL ROOIING.

The Schedule referred to in these Letters Patent and makingpart oi the sama.

Know all men by these presents: j That I, S. R. HATHORN, of the city and county of Woreester,itnd Commonwealth ofMazssachusetts, have invented certain new and useful Improvements in Slate and Metal Roong; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a view of so much of a roof as is necessary to illustrate my improvements, and

Figure 2 represents a Vertical section of the same through the slating.

To enable those skilled in the art to which my invention belongs,`to make and use the same,`I will proeeed to describe it more in detail.

The natine of my invention consists in the combination, withslates, of pieces of sheet-metal, constructed in the manner shown, and as hereafter described.

It also consists in the peculiarly-constructed metallic joint-pieces, as hereafter set forth.

In the drawings- A indicates the enclosing boards of the roof, to which the slates B areI secured by nails c.

Strips cf'metal D are placed beneath the joints between the slates, as shown in the drawings, their upper ends being bent in form of hooks e, which hook on to the top edges of the slates B, thus preventing the stu'ps of metal from sliding out of place.

'The strips D may be made of copper, tin, zinc, or

any other suitable material, and may be made either l roofs wherethe inclination is less than thirty degrees.

The old method of laying slate roofing, required slates long enough to lap under the v second course, above, from one to two inches, according, to circumstances, making the slates of the size indicated by red lines at G, iig. 1. This is necessary to protect the joints.

But withy my method of combining slate and metal, the slates may be made much shorter, as shown by dotted lines at H, iig. l, thereby lnakinga saving of nearly one-third ofthe amount of slate required, while at the same time a firmer roof is produced.

l Having described my combined slate 'and metal roofing,

What I claim therein as new, and of my inveutioxn 4and desire to secure by Letters Patent, is

purposes set forth.
